Second, urban flood control and drainage planning and construction

Our city is located in the middle and lower reaches of Dongjiang River, with complex water regime, tall peaks and large flow variability. Huicheng District is sandwiched between the floods of Dongjiang River and Xizhijiang River. There are Xiaojin River, Radius Lishui, Tangchen Water, Wangjiang Water and Huangsha Water in the territory 19. There are three medium-sized reservoirs in Honghuahu, Jiaodong and Huangsha, six small reservoirs in Liantangbu and Yanglang (65,438+0) and several small reservoirs (2).

(1) flood control and drainage planning principles and standards

In accordance with the flood control plan of "taking measures according to local conditions, simultaneously storing and discharging, making overall plans and comprehensive management", and according to the natural geographical conditions of the basin and the characteristics of flood disasters, comprehensive management measures such as building reservoirs in the upper reaches, building dikes in the middle and lower reaches for flood control, digging canals to divert flood, and building drainage pump stations in dikes to drain water will be taken to gradually build a flood control and drainage system combining storage, prevention, separation and drainage. In order to reinforce the dangerous situation, meet the safety standards and improve the flood control capacity, urban areas should properly handle the relationship between flood discharge sections and urban construction in combination with urban construction.

Flood control and waterlogging control standards are in accordance with Guangdong flood control (tidal) standards and waterlogging control standards (Guangdong Hydropower General Word [1995] No.4), and the south dike and north dike of Huizhou levee are reinforced and constructed in accordance with 100 once-in-a-year urban flood control standard (after flood regulation of three upstream reservoirs), and the drainage standard is 65438+24 hours in 00.

Fourth, the existing problems and countermeasures

(1) After the completion of Dongjiang Water Control Project, the low-lying areas on both sides of the reservoir will be flooded, which will put some pressure on flood control and drainage in Huizhou City. At present, Huizhou Huayu Water Resources and Hydropower Survey and Design Company has been entrusted to undertake the system design of upstream drainage construction project affected by water storage of Dongjiang Water Control Project, and the preliminary design scheme was submitted to the Provincial Water Resources Department for review in July 2005.

(two) due to the adjustment of some regional functions and the interconnection of various plans, the final results of the special planning for drainage and flood control cannot be submitted. The Municipal Planning and Construction Bureau and the Municipal Water Conservancy Bureau are working closely with the design unit to submit the results on time.

(3) The land ownership of Shuikou Town Sewage Plant site has not been finally solved, and the land procedures of Jinyuan Sewage Plant site have not been perfected, which directly affects the follow-up work of the project. At present, Huicheng District Government, Municipal Bureau of Land and Resources, Shuikou Town Government and Xiaojinkou Town Government are actively coordinating to solve the problem as soon as possible.

(4) Pipe network construction sites are mostly located in densely populated urban areas, which are limited by the site. Underground pipelines are relatively complex and the relocation work is heavy. In addition, the recent rainstorm and high flood have affected the progress of some projects to some extent, and the progress of some projects is relatively slow. The Municipal Public Utilities Bureau and related construction units are adjusting the construction time, increasing the number of construction personnel and equipment, and ensuring that the project construction is completed on schedule with good quality.
